Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable tie mounts with adhesive bonding surfaces face issues of inconsistent adhesive thickness and excess weight due to excess adhesive, which is problematic for weight-sensitive applications like aerospace and space-bound vehicles, and lack features to achieve optimal bond-line thickness without glass beads.
Innovation Solution
A cable tie mount with a bottom surface featuring a plurality of nubs or protrusions of predefined dimensions to define the bond-line thickness, allowing for optimal adhesive application without glass beads, and optionally including grooves for weight reduction and a single-piece molded top and bottom surface for structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If adhesive is applied without predefined thickness control, then adhesive application is simple, but adhesive thickness becomes inconsistent and excess adhesive increases weight
Solution Approach 1:
The bonding surface is pre-formed with protrusions during the molding process to define the adhesive layer thickness before adhesive application. This preliminary structural preparation ensures consistent adhesive thickness without requiring complex application controls or post-processing adjustments.
Solution Approach 2:
The bonding surface structure is modified by adding protrusions that physically constrain the adhesive layer thickness. This changes the geometric parameters of the bonding interface, ensuring that the adhesive layer maintains a predefined thickness regardless of application variations.
2Manufacturing precision
If glass beads are added to adhesive to control thickness, then dimensional standard is provided, but adhesive weight increases and curing time increases
Solution Approach 1:
The thickness control function is extracted from the adhesive formulation (glass beads) and transferred to the bonding surface structure (protrusions). This removes the need for heavy glass bead additives while maintaining precise thickness control, thereby reducing overall weight.
Solution Approach 2:
The protrusions on the bonding surface act as an intermediary structure that mediates between the adhesive application and the final bonded assembly. They provide the thickness control function without requiring the adhesive itself to contain thickness-defining additives like glass beads.
3Reliability
If applicator is used to apply adhesive and pressure, then proper seating is ensured, but installation time and process complexity increase
Solution Approach 1:
The bonding surface protrusions are designed to self-align and self-seat the cable tie mount during application. The protrusions physically guide the mounting process and ensure proper positioning without requiring external applicators to apply pressure or adjust alignment, thereby speeding up installation.
Solution Approach 2:
The protrusions are pre-formed on the bonding surface to create a self-aligning interface. This preliminary structural preparation ensures that when the cable tie mount is applied, it naturally seats correctly on the protrusions, eliminating the need for subsequent alignment adjustments or pressure application tools.
4Reliability
If excess adhesive is applied to ensure coverage, then bonding coverage is sufficient, but weight increases cumulatively in large-scale applications
Solution Approach 1:
The bonding surface geometry is changed by adding protrusions that define a specific adhesive layer thickness. This parameter change ensures that the adhesive layer is neither too thin (insufficient coverage) nor too thick (excess weight), providing optimal coverage with minimal adhesive material.
Solution Approach 2:
The protrusions create localized adhesive pockets between themselves and the mounting surface. This localizes the adhesive application to specific areas where bonding is needed, ensuring sufficient coverage while minimizing adhesive in non-critical areas, thereby reducing overall weight.
